SPECIFICATION forming part of Letters Patent No. 585,654, dated July 6, 1897..

Application filed April 10, 1897. Serial No. 631,519. (No model.)

To all whom it may concern: sides of thill-iron 6 are the pivotal pins 6, 59

Be it known that I, JAMES E. ORYDERMAN, which are adapted to fit in the half bearings a citizen of the United States of America, reor sockets 7 8, formed in the ears 3 4, and in siding at Troy, in the county of St. Croix order to prevent the thill from slipping from and State of Wisconsin, have invented oerthese sockets I provide the jaws 9 10, pivoted tain new and useful Improvements in Thillto the base-plate by the bolts 11.

proof, and, fourth, they can be manufactured in large quantities at but a slight advance over the cost of the ordinary form.

It will be observed from the above that slight details of construction may be varied, such as the proportion and position of the elements, and slight additions and omissions may be made, such as the one described of adding the spring to prevent rattling, and yet the spirit of my invention will not be departed from. For instance, the plate 17" may be provided with a spring-tongue 18 to engage and press the thill-iron to prevent rattling. When this plate is used, the thill-iron is forced under the tongue, or, if necessary, the plate may be removed for the purpose of inserting the thill-iron.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a thill-coupling, a base-plate, ears projecting outward therefrom, said ears having half-bearin gs formed on their inner sides, spring-pressed jaws pivoted to said plate and extending forward completing the upper portion of said bearings, said jaws having slots formed therein with slanting bottom walls directly above the bearings, and a thill-iron having pivotal pins to fit in said bearings, substantially as described.

2. In a thill-coupling, a base-plate, ears projecting forward therefrom, said ears having half-bearin gs formed on their inner sides, jaws pivoted to said plate and extending forward completing the upper portion of said bearings, said jaws having slots with slanting bottom walls formed directly above the bearings, a lug formed on the plate between the jaws, a spring pressing the rear part of said jaws outward, and a plate having a tongue covering the space left between the jaws, substantially as described. v

In testimony whereof I affix my signature in presence of two witnesses.

JAMES E. ORYDERMAN.
